FindBacktrace
Find provider for backtrace(3).
Checks if OS supports backtrace(3) via either libc or custom library.
This module defines the following variables:
- Backtrace_HEADER
- The header file needed for backtrace(3). Cached.
Could be forcibly set by user.
- Backtrace_INCLUDE_DIRS
- The include directories needed to use backtrace(3) header.
- Backtrace_LIBRARIES
- The libraries (linker flags) needed to use backtrace(3), if any.
- Backtrace_FOUND
- Is set if and only if backtrace(3) support detected.
The following cache variables are also available to set or use:
- Backtrace_LIBRARY
- The external library providing backtrace, if any.
- Backtrace_INCLUDE_DIR
- The directory holding the backtrace(3) header.
Typical usage is to generate of header file using configure_file()
with the contents like the following:
#cmakedefine01 Backtrace_FOUND
#if Backtrace_FOUND
# include <${Backtrace_HEADER}>
#endif
And then reference that generated header file in actual source.
